Pretend for a moment we are talking about stolen bicycles. When someone is in possession of such stolen property and the owner finds out who it is, law enforcement confiscates the property so the courts can return it to whoever is found to be the lawful owner…the bicycle itself gets returned to the owner, regardless of how much the current possessor then bicycle may have paid for it. Nobody refunds the purchaser…the legal redress for the guy who “bought” a bike that wasn’t lawfully sold now has to go to the seller to seek reimbursement…
This is very different from how stolen money would work. If you got paid for labor and the payment was stolen dollar bills, and you had no idea the dollar bills were stolen, that money is yours…this is the exact opposite of the bicycle example. In the dollar example, the victim must find the bad guy and seek legal redress from the bad guy directly.
